Re: [Xen-users] Newbie question on network and VM management

[Tengiz Dawkins <tengiz.dawkins@xxxxxxxxx>]

thanks a lot! I have one more question: should I do any specific tuning of Xen/Dom0 for my config? That will be 64+ core, 1TB RAM, 1.2TB SDD storage

host. What is the best version/release/flavour I should use to build a rock solid system for 30+VMs?

ovs is certainly more configurable than Linux bridge for this sort of
thing, I don't know the specific recipe to achieve what you want but I'm
sure it can be done.

Likewise for Linux brudge, Sarah's suggestion looks plausible to me,
although it will broadcast everything everywhere, whereas you probably
want to figure out a way to send the packets only to the intended target
plus the IDS, which would be easier
